This is not hate, this is normal people reaction on someone who has achieved something big in a questionable way. I believe no one would say that Edwards took that beating during all round on purpose to put Usman cautiousness to sleep and due to perfect timing landed that high kick. A lot of people think it was a pure luck or coincidence. Like Aljo got his belt almost accidentally. People will accept Edwards as a champ when he makes a title defence or has another fight with Usman.
I really think it was a coincidental win on Leon Edward's part, Kamaru Usman was really winning that fight being dominating the entire 3 rounds even if he lost the last round Usman still wins this but that feint hook kick is what I want to call it, was really on timing and the strength could really hurt and gets out cold Leon Edwards, for me it was luck he surely conditioned Kamaru Usman with that left hook for him to get caught but I think it was a last-ditch effort for Leon Edwards in winning this and for his surprise it works
The Khamzat vs Nate may be different, imo.
Nate is actually a fan favorite which could be the reason why he was pulled up to fight upstairs even though he is way below the rankings. Dana White's dislike of him is not in the formula, again it's all about the money that will come in when you put a fighter that has a broad amount of fans.
Like I have said Dana White is all for the money nothing more nothing less, and because of that much Support Nate Diaz has all of those fans that will surely avail and watch that fight against Khamzat Chimaev to surely support him, I think that is what Dana White is after, but again I may be wrong, but the following fight it will all go down into how good Chimaev can be, and how can Nate Diaz take on that monster on grappling, the way he manhandle Li Jingliang inside the ring while having a conversation with Dana White is really superb, he can sure do that to Nate Diaz,
